dc.description.abstractThis study was aimed to present a Technical loss analysis of the Provincial Electricity Authority (PEA) in Hatyai. To determine the technical loss in the distribution system included are Transmission Line Losses, Power Transformer Losses, Distribution Line Losses and Low-voltage Transformer and Distribution Line Losses. It was found that Low-voltage Transformer and Distribution Line Losses had a maximum value of 79 % and Technical loss was at 3.43. So in controlling or decrease Technical loss, the appropriate and correct method had to be selected by investigating both cost and worth. This study was also to determine distribution line losses by electrical model and to report on the power losses evaluation method as an improvement method to reduce the investigation cost for both transformer and capacitor selection. The study further aims at increasing the efficiency and reliability of the distribution system by reducing Technical Losses by increasing feeder size, power factor correction, reducing feeder impedance, lower transformer losses. It was discovered that line losses have much value at the end line. This was found to decrease when loads have constant distribution and are near the source. That is, line losses have lower value when lead lines have a larger size. Both load distribution and lead line sizes were observed to affect distribution line losses.
